There are plenty of bikes that will hit 110 from a dead stop in fifty yards. Not disputing antibody, just saying.
Whether or not he was on one is a different story altogether, and ability does not guilt make.
Having done wreck rebuilds on plenty of bikes, I can say that any vehicle can have the Speedo stop anywhere if mechanical damage is a factor, and some gauges will hold final speed at shut off and some will not. It just depends on the manufacturer design and holds true for any non mechanical gauge.
I've seen Harleys that were parked when hit, registering triple digit speeds on the dead Speedo.
